Abstract

A VIDEO CODING TECHNIQUE HAVING A PREDICTION-BASED BASE LAYER (31) AND MOTION COMPENSATION WITHIN A FINE GRANULAR SCALABLE CODED ENHANCEMENT LAYER (32). IN ONE EMBODIMENT, THE VIDEO CODING TECHNIQUE INVOLVES A TWO-LOOP PREDICTION-BASED ENHANCEMENT LAYER INCLUDING NON-MOTION-PREDICTED ENHANCEMENT LAYER JE AND P-FRAMES AND MOTION-PREDICTED ENHANCEMENT LAYER B-FRAMES. THE MOTIONEPREDICTED ENHANCEMENT LAYER B-FRAMES ARE COMPUTED USING: 1) MOTION-PREDICTION FROM TWO TEMPORALLY ADJACENT DIFFERENTIAL 1- AND P- OR P- AND P$RAME RESIDUALS, AND 2) THE D IFFERENTIAL B-FRAME RESIDUALS OBTAINED BY SUBTRACTING THE DECODED BASE LAYER B-FRAME RESIDUALS FROM THE ORIGINAL BASE LAYER B-FRAME RESIDUALS. IN A SECOND EMBODIMENT, THE ENHANCEMENT LAYER FURTHER INCLUDES MOTION-PREDICTED ENHANCEMENT LAYER P-FRAMES. THE MOTION- PREDICTED ENHANCEMENT LAYER P-FRAMES ARE COMPUTED USING: I) MOTION-PREDICTION FROM A TEMPORALLY ADJACENT DIFFERENTIAL I- OR P-FRAME RESIDUAL, AND 2) THE DIFFERENTIAL P-FRAME RESIDUAL OBTAINED BY SUBTRACTING THE DECODED BASE LAYER P-FRAME RESIDUAL FROM THE ORIGINAL BASE LAYER PFRAME RESIDUAL.
